Description

Fastening module for fastening elevator rails

The present invention relates to an elevator system comprising a fastening module used to fasten a rail foot of an elevator rail to a fastening plane, and elevator rails mounted on an elevator shaft or the like using fastening modules of this type. The invention also relates to a method for fastening rail feet of an elevator rail, carried out using fastening modules of this type. Specifically, the invention relates to the field of elevator systems installed in high-rise buildings and spanning multiple floors.

DE-AS 1 139 254 relates to a guide-rail fastening device for attaching guide rails of elevators to a support structure. This is based on the knowledge that it is advantageous to enable relative upward movement of the guide-rail sections when buildings settle. In order to make it easier for the building and the guide rail to move perpendicularly relative to each other, fastening holes in the form of slots are made in the support plate into which bolts for guide-rail clamps are inserted, which clamps extend along its longitudinal axis. are removed from the adjacent ridge wall in an upward direction, the guide-rail clamps elastically contact the flanges of the guide rail. If the length of the guide rail increases due to thermal expansion, the force transmitted to the bolts moves the slideably aligned rail-fastening device upward, reducing the friction between the guide-rail clamps and the guide rail, which This makes it easier for the guide rail to move vertically upward relative to the guide-rail clamps.

The guide-rail fastening device known from DE-AS 1 139 254 has the disadvantage that direction-dependent friction changes occur. Specifically, if the opposite relative movement occurs, for example due to temperature-related shrinkage of the guide rail, the bolts are moved downward into the slots, which increases the friction between the guide-rail clamps and the guide rail and the fastening device. Prevents relative vertical movement between and rail. Moreover, each movement of the bolt in the slot also leads to a change in holding force or play in the guide rail on the fastener, which is undesirable.

CH-PS 484 826 discloses a fastening device for guide rails of elevators. This fastening device, when fastening the guide rails of elevators, needs to take into account that when the temperature changes, the length of the guide rails changes and the brickwork of the shaft may shrink over time. It is based on knowledge. Accordingly, longitudinal adjustment is permitted between the guide rails and the brickwork of the shaft. The proposed fastening device sufficiently holds the guide rails in the horizontal direction and does not clamp the rails tightly in the vertical direction. For this purpose, rail clamps are placed on either side of the guide rail. The rail clamp consists of two circular disks of different diameters lying coaxially on top of each other and transitioning from one to another in a conical shape. To set the clearance, a plurality of spacer disks are inserted between the support plate and the rail clamp.

In the fastening device known from CH-PS 484 826, it needs to be assembled from a plurality of parts, and the technician has to set the clearance by means of spacer disks.

US 3,982,692 discloses a fastening means used to fasten the sides of an elevator rail with a T-shaped profile to a support, which takes place so that a relative movement of the elevator rail is possible, for example to compensate for building subsidence. Here, lateral movements are prevented and a limited movement of the elevator rail away from the support is possible against the preload force of the spring tabs.

The fastening known from US 3,982,692 has the disadvantage that the limited but possible adjusting movement allows twisting of the elevator rail along the longitudinal axis, which means, for example, that during operation transverse forces force the elevator rail from the elevator car or counterweight. causes a corresponding curvature of the guide tracks provided on the elevator rail. This is generally undesirable.

EP 0 448 839 A1 discloses a fastening device for guide rails of elevators. In known fastening devices, changes in the preload force of the rail clamps can be achieved by semicircular profiles used as linings for guide rails with different thicknesses. However, for this it is necessary to determine which semicircular profile is required and needs to be transported before the elevator system is installed.

US 6371249 B1 discloses a rail clamp in which a clamping bracket guided in a slot disposed on the side of a guide rail can be pivoted from the outside by a foot of the guide rail, and the guide rails can be clamped on both sides. To optimize mounting, the lateral slots are placed at an angle of 45°. Laterally arranged slots extending at an angle require a lot of space and weaken the cross-section of the corresponding wall plate.

EP 2174902 A1 discloses another rail clamp suitable for interconnecting a plurality of rails. Here, the rail clamp is moved laterally in a slot made in the side of the guide rail. The lateral holding force for holding the rail is in this case provided solely by the frictional forces of the fastening parts.

Known configurations are not satisfactory. The configurations, for example, require a lot of space, the configurations insufficiently transmit the required forces, or the configurations need to be assembled on site, which is complicated, or the configurations are at least partially required to insert the elevator rail. It needs to be broken down into

In an elevator system installed in a building, the elevator rails may be fastened directly or indirectly to the building wall. Elevator rails or counterweights, used for example as guide rails for an elevator car, may in this case extend over the entire travel path of the elevator, which often roughly corresponds to the height of the building. In this case, the elevator rails need to be fastened sufficiently tightly within the building that they can reliably absorb the guiding forces. However, the height of a building may change over time. Buildings shrink, for example, because they dry out and settle. A building's temperature and solar radiation can also change its height. Accordingly, the elevator rails can move relative to the building and in particular the height of the building can be reduced relative to the elevator rails. To prevent deformation of the rail sections in this case, the fastening points on the elevator rails are designed so that length compensation is possible, but at the same time there is sufficient fastening to absorb the guiding force.

One problem solved by the present invention is to provide a fastening module for an elevator rail, an elevator system comprising a plurality of fastening modules, and a method for fastening the elevator rail, all of which have an improved configuration. Specifically, one problem solved by the present invention is to provide a fastening module for an elevator rail, an elevator system comprising a plurality of fastening modules, and a method for fastening an elevator rail, allowing improved fastening. , this makes it possible for the elevator rail to carry out relative movements along its extension and also prevent movement or rotation in an imaginary plane perpendicular to the extension, and allows the technician to carry out assembly in a simple and compact manner. .

Solutions and proposals for a corresponding fastening module, a corresponding elevator system and a corresponding method that solve at least part of at least one of the challenges posed are provided below. Moreover, advantageous additional or alternative refinements and embodiments are specified.

In one solution, a fastening module used to fasten a rail foot of an elevator rail to a fastening plane comprises: a first fastening device fastened to the fastening plane and used to retain a first side of the rail foot during assembly; , may be designed to include a second fastening device fastened to the fastening plane and used to maintain a second side of the rail foot, the second fastening device being movable at least substantially parallel to the fastening plane, and At least one element of the second fastening device rotates about an axis of rotation of the second fastening device at least substantially perpendicular to the fastening plane, on an upper side of the rail foot from the outside laterally of the rail foot. The element may, upon assembly, interact with the upper side of the rail foot facing away from the fastening plane.

The elevator rail itself is not part of the fastening module in this case. Fastening modules can be pre-assembled in a manufacturing plant and produced and distributed as units. When assembling an elevator system, a plurality of fastening modules are used to mount the elevator rails to the elevator shaft. During assembly, single elevator rails, which may be an integral part of an assembly of elevator rails assembled to form a continuous elevator car rail, counterweight guide rail, etc., may each be fastened using at least one fastening module. A typical integral section of elevator rail is typically approximately 5 meters in length. Each part is generally fastened to the shaft wall by one or two fastening modules, or more fastening modules, and the parts are interconnected by connecting plates, producing a cohesive row of elevator rails. After assembling the elevator system, this type of elevator car guide rail or counterweight guide rail results from the assembly of elevator rails that are successively arranged along the longitudinal axis and fastened to the elevator shaft or the like by a plurality of fastening modules.

In one solution, an elevator system is proposed comprising at least one assembly of elevator rails arranged continuously along a longitudinal axis and a plurality of fastening modules, which fastening modules are used to fasten rail pits of the elevator rails.

In the proposed method for fastening the rail foot of an elevator rail, which is carried out using one or more fastening modules, the fastening module is mounted or pre-mounted on the shaft wall. The first side of the rail foot is inserted between the contact area and the support area of the first fastening device of the fastening module, and the second side of the rail foot is disposed between the contact area and the support area of the second fastening device. is rotated and moved.

Before the elevator rail is placed on the fastening module, the fastening module is not necessarily securely mounted on the support structure, shaft wall, etc. Nevertheless, it is advantageous if one or more fastening modules are fixedly mounted on the elevator shaft, or at least are pre-mounted. The elevator rail is then positioned on one such fastening module, or preferably on a plurality of fastening modules, such that the first side of the elevator rail fits into the first fastening device or the first fastening devices of the plurality of fastening modules. Lose. Advantageously, the second fastening device or second fastening devices of the plurality of fastening modules can then be positioned in the proposed manner. This gives rise to advantageous assembly options that the technician can easily perform using fewer tools.

The element of the second fastening device is a support element, which interacts with the upper side of the rail foot during assembly and whose support area is advantageously arranged at a predetermined distance from the fastening plane during assembly. The upper side of the rail foot can be oriented by the support area of the second fastening device, preferably by the support area of the support element of the first fastening device. As a result, the tracks in the elevator rails, especially in the rail head of the elevator rail, are also oriented in space.

Additionally, the second fastening device comprises compensating means with a contact element, wherein a contact area is advantageously formed on the contact element, wherein the second side of the rail foot is, during assembly, in contact with the contact area of the contact element and the second fastening device. 2 may be arranged between the support areas of the support elements of the fastening device. Therefore, compensating means with a contact element can be provided in the first fastening device, where a contact area is also formed in this contact element and the first side of the rail foot is, when assembled, in contact with the contact area of the contact element and the first fastening device. It may be arranged between the support areas of the support elements. Specifically, adjustment to different rail fits can here be carried out using compensation means. Additionally, the compensating means can make it possible to fasten the rail foot in a simple manner. In particular, the rail foot can in this case be fastened without using any additional tools. This means modular configuration is possible. In particular, fastening modules can be manufactured at a manufacturing plant for a specific rail type. It is particularly easy to assemble elevator rails of this rail type. Here, a certain level of tolerance compensation, resulting from manufacturing-related deviations, in particular in the rail fit of the rail type, can be allowed.

Here, the compensating means are designed so that the retaining dimensions provided between the contact area and the support area can be adapted to the required retaining dimensions of the second side of the rail foot, the second side of the rail foot comprising: During assembly, it is particularly advantageous to remain between the contact area and the support area. Therefore, the compensating means for the first fastening device can be designed so that the retaining dimensions provided between the contact area and the support area can be adapted to the required retaining dimensions of the first side of the rail foot, The side surface, during assembly, is held between the contact area and the support area. Changes in the required holding dimensions may be tolerance-related, for example. This particularly concerns manufacturing tolerances between individual elevator rails of a particular rail type. Depending on the design of the fastening module, however, if adaptation is possible and feasible, adaptation to different rail types can be made using compensation means.

It is also provided that the compensating means comprises a wedge element, the contact element and the wedge element being adjustable relative to each other at least approximately parallel to the fastening plane, the contact element and the wedge element being positioned in the contact area and the support. It is advantageous for the design to be such that between regions the retaining dimensions appearing at least approximately perpendicular to the fastening plane can vary. Here, the retaining dimensions can be varied so that the second side of the rail foot can be fastened without play during assembly, by moving the contact element relative to the wedge element and/or by locking the second side of the rail foot relative to the fastening plane. This is carried out by moving the contact elements. It is therefore advantageous if the compensating means of the first fastening device comprises a wedge element, and the contact element and the wedge element of the first fastening device are adjustable relative to each other at least approximately parallel to the fastening plane. In this case, the compensating means and the wedge elements of the first fastening device are advantageously visible between the contact area and the support area at least approximately at a right angle to the fastening plane and are such that the first side of the rail foot has a play during assembly. It is designed so that the retaining dimensions, which make it possible to fasten without, can be varied by moving the contact elements relative to the wedge elements of the first fastening device and/or by moving the contact elements of the first fastening device relative to the fastening plane.

Here, due to the design, the wedge element can remain fixed in the adjustment direction of the contact element when the contact element is adjusted for mounting the rail foot. This allows simple handling by technicians. Additionally, when the rail foot is in direct contact with the contact element due to the potentially engaging contact element, the contact element is prevented from being displaced, for example when the rail foot moves.

Furthermore, it is advantageous for at least an element of the second fastening device to be rotated by at least approximately 90° about the axis of rotation of the second fastening device, on the upper side of the rail foot from the outside in the lateral direction of the rail foot. . In particular, the second fastening device can be rotated entirely about the axis of rotation. When the rail foot is in place, this allows the rail foot to be gripped or enveloped. This means that the installation space required by the fastening module is optimized. Advantageously, the first fastening device cannot rotate in this way. This makes it easier to manufacture the fastening module and also allows one or more first fastening devices of one or more fastening modules to be available such that the first side of the rail foot is to some extent mounted inside. When the rail foot is positioned with the first side to the at least one first fastening device of the at least one fastening module, assembly can continue on the second side. At appropriate times, assembly steps can be carried out on the first and second sides of the rail foot to retain and fasten the rail foot in position, for example by means of suitable compensation means.

Advantageously, a guide is provided by which the second fastening device is guided along a guide track in the fastening plane, the guide track allowing the second fastening device to perform a predetermined assembly of the second side of the rail foot. and an advancing portion oriented so as to be able to move at least substantially directly toward the position. A predetermined assembly position is here understood to mean a position on the elevator rail that has been or is to be reached during assembly. This may relate, for example, to the position and orientation of the top side of the rail foot and, therefore, generally to the arrangement of the tracks formed on the rail head in the elevator shaft. The advancing part of the guide track allows the second fastening device to be brought close to the rail foot, firstly for short sections of the guide track.

Additionally, a guide is provided, whereby the second fastening device is guided along a guide track in the fastening plane, the guide track allowing the second fastening device to be positioned at a predetermined assembly position on the second side of the rail foot. It is advantageous to include an advancing portion oriented so that it can move towards and also parallel to the longitudinal axis of the rail foot specified by the assembly position. In contrast to the advance section, which is advantageously provided similarly, access is made to the rail foot and the second side of the rail foot is thus more encompassed by the longer section of the guide track. This configuration may also make it easier to insert the rail foot between the first fastening device and the second fastening device. Accordingly, the first fastening device is positioned to be substantially fixed relative to the fastening plane. This means that the first fastening device is not movable and is not preferably rotatably arranged.

Specifically, when projected onto the fastening plane, the guide track has a first inclination along the advancing portion that is at least approximately 90° and/or is always less than 45° along the approaching portion with respect to the longitudinal axis of the rail foot specified by the assembly position. It is advantageous to have a second slope. For example, here the second slope can also vary at the approach. However, the second slope may also be at least approximately constant along the approach. The guide track extends at least approximately in a straight line from the access section. Advantageously, the guide track may comprise a bend between the advancing portion and the approaching portion. This makes it easier to design the guide, which also makes it possible to predetermine the linear movement of the second fastening element along the guide track during assembly. However, in a modified embodiment, a curved transition can also be provided, for example between the advancing part and the approaching part. The required fastening dimensions can thus be optimized.

In an advantageous embodiment, a base plate is provided on which the fastening plane is located at least indirectly. In this case, this base plate may be designed to be curved into an L shape, a fastening plane may be provided on one leg, and one or more options for fastening to a support structure, etc. may be provided on the other leg. The guide for the second fastening device can advantageously be made in the base plate in the form of a guide cutout. Furthermore, the guide cutouts made in the base plate here advantageously comprise slots with or without rounded transitions. The fastening means of the second fastening device can for example extend through a slot of this type and interact with the guide cutout for guiding purposes. By the base plate curved into an L shape, the fastening module can be easily fastened to the shaft wall. Therefore, the holes arranged in the part of the base plate bent upward make it possible to adjust the fastening in the shaft wall, so that the whole of the elevator guide rail can be oriented in a straight line after fastening to the fastening module.

In an advantageous embodiment, the slot is designed to have a bend along the guide track. Additionally or alternatively, the slot advantageously consists of at least two rectangular shapes rotated relative to each other. These rectangular shapes are oriented parallel to the fastening plane and rotated relative to each other. As a result, the advance and approach parts can be manufactured along two rectangular shapes.

In a variant embodiment in which the sides 7, 8 are exchanged, the fastening devices 15, 16 are therefore also exchanged.

The first fastening device (15) comprises an L-shaped support element (17), whose distal face (18) defines a fastening plane (4). In this embodiment the support area 20 in the form of a protrusion 20 is formed in the part 19 of the support element 17 . The support element 17 also includes a clearance 21 . Another clearance 22 in the support element 17 is designed as a hole 22.

The first fastening device 15 also comprises in this embodiment compensating means 23 comprising elements 24 , 25 . In this embodiment, the element 24 is designed as a contact element 24. Element 25 is designed as a wedge element 25. A contact area 26 in the form of a protrusion 26 is formed on the contact element 24 . The adjustment direction 27 oriented parallel to the fastening plane 4 is predefined for the contact element 24 . Additionally, an adjustment tab 28 is formed on the contact element 24, which allows the technician to adjust the contact element 24 in the adjustment direction 27. The contact elements 24, 25 extend through a clearance 21 in the support element 17. In this embodiment, the wedge element 25 is arranged to be fixed relative to the fastening plane 4 and the contact element 24 can be adjusted in the adjustment direction 27.

Furthermore, the first fastening device 15 comprises a sleeve 29 that can be annularly closed or open about its periphery. The support element 17 is supported in the fastening plane 4 or the base plate 5 by the end face 18 as well as in the fastening plane 4 or the base plate 5 by the sleeve 29 . There is also a lateral support area (30) in the sleeve (29) for the rail foot (6).

In a variant, the wedge element 25 may also be fastened directly to the fastening plane 4 by means of the sleeve 29 . The height of the sleeve 29 is in this case reduced by the thickness of the wedge element 25.

The first fastening device 15 also comprises fastening means 31 , which allow for example screws to be used for fastening to the base plate 5 . Using the fastening means 31 , the support element 17 is securely fastened to the base plate together with the sleeve 29 and preferably with a wedge element 25 positioned thereunder.

The second fastening device 16 therefore comprises a support element 17A on which an end face 18A is formed. A support area 20A in the form of a protrusion 20A is formed in the portion 19A of the support element 17A. Clearances 21A and 22A in the form of holes 22A are also formed in the support element 17A.

Additionally, a contact area 26A in the form of a protrusion 26A is formed on the element 24A. The adjustment direction 27A is predetermined for the contact element 24A. Here, an adjusting tab 28A is formed on the contact element 24A. Additionally, the second fastening device 16 includes a sleeve 29A. A support area 30A is created in the sleeve 29A. Wedge element 25A is also sometimes positioned below sleeve 29A. Furthermore, the second fastening device 16 includes fastening means 31A.

It is clear that the operating modes and characteristics described for one of the fastening devices 15, 16 can also in each case be at least partially transferred to the other fastening device 15, 16.

When assembled, the upper side 13 of the rail foot 6 contacts the support area 20 of the first fastening device 15 on one side and the support area 20A of the second fastening device 16 on the other side. do. This sets the orientation of the elevator rail 2 in the elevator shaft 35. As a result, the tracks 36, 37 formed in the rail head 10 are also set in terms of extension through the elevator shaft 35. Depending on the design, another fastening module corresponding to the fastening module 1 may also be required here to set the position of the elevator rail 2 in the elevator shaft 35 . One or more fastening modules (1) may be provided on the elevator rail (2).

In the assembled state in which the elevator rail 2 is fastened to the fastening plane 4 by the fastening module 1, the contact areas 26, 26A of the contact elements 24, 24A are also connected to the rail foot 6. It contacts the lower side (12) of . When doing so, there is a kind of clamping grip between the contact area 26 and the support area 20, respectively, and between the contact area 26A and the support area 20A, in which the first grip of the rail foot 6 The side 7 and the second side 8 are each gripped.

A retaining dimension 38 is created between the contact area 26 and the support area 20, at right angles to the fastening plane 4. This holding dimension 38 decreases due to the wedge shape of the wedge element 25 when the contact element 24 is adjusted in the adjustment direction 27. In the assembled state, the holding dimensions 38 are equal to the required holding dimensions 38 which are determined by the geometry of the rail foot 6. In this embodiment, the same retaining dimensions 38 are also created in the second fastening device 16 . However, in principle, other retaining dimensions 38 could also be created in the fastening devices 15, 16. In general, the required holding dimensions 38, depending on the rail foot involved, vary from one elevator rail 2 to another due to manufacturing tolerances. Using the described adaptation mechanism, the holding dimension 38 can be set to the required holding dimension 38 in each case.

In this embodiment, the gap 33 between the support areas 20A, 20 of the support elements 17, 17A and the fastening plane 4 is fixed in the assembled state. The holding dimension 38 can be set during assembly of the elevator rail 2 by means of compensation means 23, 23A.

Figure 2 is a three-dimensional view of the fastening module 1 shown in Figure 1, according to an embodiment, in a ready-to-assemble position. The fastening module (1) can be pre-assembled in this form at the manufacturing plant. Other parts, for example used to fasten the module to the shaft wall, are sometimes included or pre-assembled if necessary. The base plate 5, which in this embodiment is curved into an L shape, includes legs 40, 41. Here, the leg 40 is provided with suitable assembly options 42 in the form of slots 42 and the like. As a result, it can be screwed to the support structure. Figure 2 shows the axis 43 and the longitudinal axis 44. In this case, the longitudinal axis 44 is the axis along which the assembled elevator rail 2 extends. The longitudinal axis 44 is substantially parallel to the fastening plane 4, including when the longitudinal axis 44 lies in the fastening plane 4. Moreover, the axis 43 extends parallel to the fastening plane 4 and at right angles to the longitudinal axis 44. In the prepared position, the first fastening device 15 is oriented relative to the axis 43 so that the adjustment direction 27 is parallel to the axis 43 . The first fastening device 15 is in this case connected to the base plate 5 by fastening means 31, and no rotation or movement is possible. When the locking means 32 is loosened, the contact element 24 can nevertheless be adjusted in the adjustment direction 27 . When tightening the locking means 32, the contact element 24 is also locked.

In the prepared position, however, the second fastening device 16 is oriented along the longitudinal axis 44 such that the associated adjustment direction 27A is parallel to the longitudinal axis 44 . This means that the angle 45 between the axis 46 and the axis 43 in the adjustment direction 27A is at least approximately 90°. During pre-assembly, the angle 45 of approximately 90° is not a predetermined value. Instead, the fastening device 16 is loose, ie mounted movably in the fastening plane 4 .

It is clear that locking means 32A (Figure 4) are also provided in the second fastening device 16. Locking means 32A of this type may also be fitted later if required. However, locking means 32A of this type can also be mounted on the second fastening device 16 in advance in the fastening module 1 prepared for assembly.

Figure 3 shows the fastening module 1 and the elevator rail 2 shown in Figure 2 during assembly. Here, the elevator rail 2 is inserted between the fastening devices 15, 16. Due to the position of the second fastening device 16 rotated by 90° and a certain amount of clearance, the rail foot 6 can be inserted into the position shown without disassembling the first fastening device 15. The first side (7) of the rail foot (6) clamps between the support area (20) and the contact area (26) of the first fastening device (15) in the adjustment direction (27) or to some extent along the axis (43). The first side 7 of the elevator rail 2 is in contact with the support area 30 of the support element 17 .

The second fastening device 16 is initially held loosely in the prepared position, also as shown in FIG. 2 .

FIG. 4 is a schematic view of the fastening module 1 and the elevator rail 2 shown in FIG. 3 when assembled, viewed from the viewing direction indicated by IV. The base plate 5 includes guide cutouts 50 in the form of slots 50, whereby the guide 50 is formed. The guide track 51 is formed by the geometry of the guide cutout 50 and its interaction with the fastening means 31A. The second fastening device 16 can be moved along the guide track 51 relative to the fastening plane 4 . Moreover, the second fastening device 16 can in this embodiment rotate about a rotational axis 52 which coincides with the axis 52 of the fastening means 31A. The rotation axis 52 is oriented perpendicular to the fastening plane 4.

In a possible assembly step, proceeding from the position shown in FIG. 3 , the second fastening device 16 is initially rotated about the axis of rotation 52 . Here, the second fastening device 16 is rotated in the direction of rotation 53 (Figure 3). At the same time, the second fastening device 16 can be adjusted along the guide track 51 . In this embodiment, the guide track 51 includes an advancing portion 54 and an approaching portion 55. With respect to the protrusion of the longitudinal axis 44 and the advancing portion 54 towards the fastening plane 4 , in this embodiment a first inclination (angle) 56 of approximately 90° is created at least approximately therebetween. Therefore, at the protrusion into the fastening plane 4 , a second inclination (angle) 57 of the approach portion 55 with respect to the longitudinal axis 44 is created, which in this embodiment is significantly less than 90° and Even less than 45°. Via the advancing portion 54 the second fastening device approaches very close to the second side 8 for a short adjustment path. Then, via the access section 55 , a slower approach to the adjustment path along the guide track 51 can be achieved. Here, support of the second fastening device 16 on the side 58 of the guide cutout 50 can also be used. In particular, the second fastening device 16 is supported on the side 58 by the fastening means 31A when the technician presses the second fastening device 16 in the direction 59 parallel to the longitudinal axis 44. This makes assembly simple. By this forward movement, the second side 8 of the rail foot 6 comes between the contact area 26A and the support area 20A of the second fastening device 16. Here, the second fastening device 16 can rotate by 90° in the initial direction of rotation 53. By rotating the fastening device 16 along the guide track 51 towards the elevator rail 2, the support area ( 16 30A) is advanced towards the second side (8) of the elevator rail (2). As a result, the elevator rail 2 is guided laterally.

In particular, the support element 17A can thus be rotated on the upper side 13 of the rail foot 6 from the outside in the lateral direction of the rail foot 6 as shown in FIG. 3 . Accordingly, after the fastening means 31, 31A have been tightened, the rail foot 6 is in a simple way, with as little play as possible, as desired, in the lateral support area of the fastening devices 15, 16 shown in Figure 1. It can be fastened between (30, 30A).

In a possible assembly process, the technician can adjust the contact elements 24, 24A in the respective adjustment directions 27, 27A after the fastening means 31A has been tightened. Thereafter, locking can be performed using locking means 32, 32A. Afterwards, the rail foot (6) is fastened to the fastening plane (4) by the fastening module (1).

This fastening allows a certain amount of length compensation or movement of the elevator rail (2) along the longitudinal axis (44) relative to the fastening module (1). The holding forces applied by the fastening devices 15, 16 can be allocated in particular so as to be able to compensate for changes in length that occur, for example, due to building settlement. Here, the elevator rail (2) is allowed to slide to some extent through the fastening module (1).

In this embodiment, the guide track 51 includes a curved portion 60. In a variant embodiment, however, the guide cutout 50 may also be curved, which means that a curve 60 of this kind is omitted. Furthermore, in this embodiment, the guide cutout 50 includes edges 61, of which only one edge 61 is shown to simplify the drawing. With appropriate rounding, one or more edges 61 of this type can be omitted, or the edges 61 are then replaced by rounded transitions.

In this embodiment, the guide cutout 50 consists of two rectangles 62, 63. In this case, the rectangles 62 , 63 are oriented parallel to the fastening plane 4 and rotated relative to each other with respect to the fastening plane 4 . This rotation results in different inclinations (56, 57).

Figure 5 is a partial schematic diagram of an elevator system 3 according to a possible embodiment of the invention. The elevator system 3 includes a plurality of elevator rails 2, 2A, 2B, 2C. Here, the elevator rails 2, 2A are part of an assembly 70 of a plurality of elevator rails 2, 2A extending through the elevator shaft 35 along the longitudinal axis 44. The elevator rails 2B, 2C are part of another such assembly 71 of a plurality of elevator rails 2B, 2C. Braking and/or guide tracks 36 , 37 are created, for example, in assembly 70 , which extend at least substantially through the entire elevator shaft 35 . Tracks (36, 37) of this type are continuous for the individual elevator rails (2, 2A).

The elevator system 3 also includes an elevator car 72 and a counterweight 73, which are interconnected by support and traction means 74. By means of the assemblies 70 , 71 and possibly other assemblies of this kind, the elevator car 72 and the counterweight 73 can be guided in particular in the elevator shaft 35 .

FIG. 6 shows a detail, marked VI in FIG. 5 , of the elevator system 3 together with the assembly 70 and the fastening modules 1, 1'. The fastening modules 1, 1' comprise base plates 5, 5' which are mounted on the elevator shaft 35 by a support structure or the like. The elevator rails 2, 2A are butt-joined to each other at the interface 80. The elevator rails 2, 2A can be joined together by connecting plates 81, for example at the interface 80. As a result, continuous tracks 36, 37 are created in the assembly 70 of the plurality of elevator rails 2, 2A.

The rail feet 6, 6A of the elevator rails 2, 2A may be different, for example due to manufacturing tolerances. This may be apparent from other required holding dimensions 38 . Nevertheless, the same fastening modules 1, 1' can be used to assemble the elevator rails 2, 2A. The respective retaining dimensions 38 can be set in a custom manner in each individual fastening module 1 , 1' during assembly to the required retaining dimensions 38 , as explained with reference to FIG. 1 .

The invention is not limited to the described embodiments.
